Deriving a new authority record from a bib record and creation of 670

Description:Deriving a new authority record from a bib record and creation of 670:Creation of a 670 only happens if there is a 1## tag in the bib. It should also be created if there is a 6## 7## or 8## (except for 650 and 800)

Resolution:This is a feature - field 670 is currently only created when deriving authority record from field 1XX. Other fields do not create field 670. This field is not mandatory and in other cases should be added manually.
